Ceann Iar (Gaelic "Western Headland") is one of the Monach Isles/Heisgeir, to the west of North Uist in the Outer Hebrides.
Not unlike the Isles of Scilly, it is possible that Ceann Iar, Sibhinis and Ceann Ear formed a single body of land within historic times, and that their land area has greatly decreased due to overgrazing, and wind erosion as well.
The ship hit a mine in 1917, during World War I, off Northern Ireland, and his body had drifted all the way to here.
Strangely, this accords with the old Hebridean tradition that the sea carries the drowned home - the Monachs are Clan MacNeil territory.
The island had been settled intermittently for over a thousand years, although the main settlement was on Ceann Ear.
